Every Wednesday, Michio Kaku will be answering reader questions about physics and futuristic science.  If you have a question for Dr. Kaku, just post it in the comments section below and check back on Wednesdays to see if he answers it.

Today, Dr. Kaku addresses a question posed by Matthew Miossec: If quantum teleportation could teleport a whole human, would that transported human really be the same person or just an exact copy?
